You know, if it is going in a 4x4 shortcourse the Copperhead is great. I have a VTX10r waiting for a 550 sensored motor but this copper head is so smooth, fast and runs cool. The Copperhead has some adjustability and is just as fast as everything else on the track.

The only issue I have with my Copperhead is with the punch set high my batteries get pissy. I need some new batteries that can handle high amp draw.

The VTX speed controls are great because to can make them as smooth as you want through all the adjustable perameters.

I thought so too but I fried one on 3s. So I'm being cautious.

Sorry, I missed this one yesterday. Just ran the a Trophy race at a track last weekend finished 2nd in Pro2 with a VST 10.5. Nice combination of power and drivability.

To answer the question about why this thread is not in the Radio and Electronics section ---

because on this one we discuss more off-road related applications. we also have one in the on-road section to discuss on-road applications. Mostly what you get in the Radio/Electronics section is issues or problems to be solved. but we monitor that as well, in case any one asks about Viper products.

ok, makes sense, not a problem...

The big difference on the VTX1 is that it is 1s capable, and when running 1s, it does not require a external battery to the run the radio. It can step up the voltage for the receiver.

I know there are some setups on the forum and on the speed control pages on the website, but would be great to sticky some in the forum on website. Several different motor applications and cars. 17.5 blinky, 17.5 boosted, 10.5 (both), and mod profiles. It is hard to dig through all of the pages here and there to get ideas. just an idea.....

Hey Nikos - What's your ESC setup for Pro2 and the VST10.5?

I am hoping someone can tell me if something is possible with the dynamic brake function. I would like to set it so that I have very weak drag brake at high speed and strong drag brake at low speed. I am not sure if this is possible.

I did some experimenting by setting the drag brake to 0 and using only the dynamic brake. I set the maximum dynamic brake to 100% and trigger rpm to 2,000.. I could hear the brake working down to about the 2000 rpm and then it seemed to instantly have no brake just as I would expect.

Next, I tried maximum dynamic brake at 2% with trigger rpm at 2,000. I set the drag brake to 95% (just so I could tell it is working). The result was that I had a very strong drag brake at the high speed. I would have expected to have almost no drag brake at the high speed.

It seems that the dynamic maximum brake % is added on top of the drag brake %.

I hope everyone can understand what I am doing. If not, I will try to clarify. Thanks in advance.

I haven't tried it or looked at it closely, but from what I understand it is intended for Touring Car. Everyone said to turn that off for offroad. If I remember right, it has something to do with different brake settings at different RPM, so you could have more brakes while at a higher RPM, thus making your high speed braking and low speed braking feel similar (or different).

If you don't get any other replies, shoot me a PM and I'll dig you up an answer

Thank you for the reply.

I was fairly sure I was trying something that it was not designed to do. The reason I wanted to try this is that the drag brake seems to get weaker at lower speeds. Or, maybe, the same amount of drag brake at a lower speed just isn't as obvious as high speed. Have you noticed that the drag brake seems to disappear at low speeds?

A fairly strong drag brake helps me quite a bit with gaining more steering entering but I can't have the strong drag brake when entering a high speed turn or the car will spin.

Why don't we start by doing this. List all of your settings here and maybe we can pick out something that is causing you to get that feel.

I know that the amount of brake is pretty consistent for me, although I only run 10%. For me it's more to get the feel of a brushed motor. Some guys drive in a way that more drag brake helps them. I am working on adapting my driving style to include more drag brake because ultimately I believe it to be faster, but I'm not quite there yet.

do you guys have anyone coming to the SIGP this weekend in Tucson, AZ?

whats the standard timing setting on the vst 10.5Turn? also is it marked on the can with numbers and are these actual true timing?

easier answers first - the motors come set at 30º. And are true to settings.

Settings I used last weekend w/VST10.5 (can timing 30º):
Throttle Freq - 8000hz
Punch - 95
Power - 95 (small track turned Punch and Power down slightly)
Brake - 98%
Brake Freq - 2500 hz
Drag Brake - 20
Smart Brake - Disabled
ESC cut off - 220
Motor cut off - disabled
Battery cut off - 6.4v
Blinky mode

Set Up Pages - Looking for a better way to set up the information on the pages. Takes too long for he website people to post them like they did The IIC set ups and the files are little difficult to use in the forums. But working on it.

Not sure if anyone will be at SIGP this weekend. Being so close to the holiday's we aren't "pushing" people to races. We have from AZ drivers that may be there on their own -- but no one has mentioned it to me directly.
